This research study explores the potential of the dysfunctional ventilator weaning response (DVWR) as an accuracy predictor of successful ventilator weaning. The genesis of this research stemmed from the researcher's motivation to systematize the care of patients requiring invasive mechanical ventilation. Nurses play a pivotal role in this process, inserting and managing the tube and adapting the patient to the system, and, most crucially, to ventilator weaning. However, the extent to which nurses contribute to this process is nascent and not systematically guided by nursing diagnoses. A notable aspect of this study is the nurse's role in diagnostic decision-making and its correlation with weaning outcomes.
The objectives are to examine the association between DVWR and successful and unsuccessful ventilator weaning in ICU patients, evaluate the defining characteristics of the DVWR diagnosis as accuracy indicators of successful and unsuccessful ventilator weaning, and examine the association of the defining characteristics with the DVWR nursing diagnosis.
This is a longitudinal prospective cohort study of diagnostic accuracy using a quantitative approach.
The population included patients aged 18 years of age or older who were receiving invasive mechanical ventilation support for more than 24 hours and who were selected to initiate ventilator weaning. The data collection technique used included participant observation during all weaning attempts, clinical documentation records, and multiparametric data. The study population was divided into two distinct groups: those who underwent weaning with extubation and those who underwent tracheostomy despite undergoing ventilator weaning.
The collected data underwent rigorous analysis using Instat Graphpad® and DAG Stat® statistical software to verify several accuracy indicators, including sensitivity, specificity, predictive values, efficiency, and the diagnostic odds ratio.
